Map of Darkavir Mine
1 - Steg's treasure
At the end of the mine you'll find a chest with "Mysterious Parchment" inside.
When you leave the underground you'll encounter Steg's beloved, who will ask you to give her the document back. You can agree or refuse. If you choose the second option, you'll have to fight her. You can also use persuasion, so you'll avoid the fight and keep the map.
Whether option you choose, return to Steg to finish the mission M5(9). If you still have the map, he will let you keep it. You can find it in your backpack, in section "Consumables". After using it, Steg's family treasure will be marked on the map.
While being in Whitestone M5(4), go to the inn and talk to the barmaid Bera Grastar. You'll learn from her that she's out of meat to serve customers.
In order to get it, go to the one of nearby mines and defeat rats living there. She will be grateful for the meat.
On the floor of the inn in Whitestone M5(4) you can encounter one of the Travelers guild members. She will give you the task to steal a valuable item from mayor house.
In order to get there, you have to obtain the proper key first. You'll find it in the closet on the floor of the town hall.
Once you get underground, go forwards lockpicking doors on your way.
Eventually you'll reach a room with a locked chest. Inside you'll find document you're looking for - Confession of Mayor Taklari.
You have to bring it to Lina, who can be found near the Sun Camp M5(7). During conversation you can choose three options. If you do not want anything in exchange for the letter, she will give you average quality daggers and a bucklet. The middle dialog option doesn't change anything. If you demand money, she will give you about 5,000 gold.
On the first floor of the inn in Whitestone M5(1) you'll meet Squire Coran, who delivers notices about dead soldiers. Agree to help him in this unpleasant task.
A death notice about Joanne Gortan should be delivered to Vonne Gortan in Whitestone M5(4).
Notice about fate of Mal Dydyn is meant for Plagueshield Dydyn in Ironfast Keep M4(4).
A third san recipient can be found in Plains of Erathell Rathir. He awaits you in The Luminary Leaf.
The last person is Fridi Edstar, who is found in the inn in Mel Senshir. Once you deliver all notices, return to the quest giver to collect your reward.
In the Sun Camp you'll find a man named Harriset Donnel. Talk to him. He is looking for any iron items. If you find anything with "iron" in its name, just bring it to Harisset and you'll receive some money. This task is repeatable.
